Air conditioning system for hybrid power vehicle

Abstract

The invention provides an air conditioning system for a hybrid power vehicle. The air conditioning system for the hybrid power vehicle comprises a motor compressor, a condenser, a receiver-drier, an expansion device, an evaporator, a heater, a blower, an air conditioning control module, an in-vehicle temperature sensor and an air conditioning switch, wherein the air conditioning control module is connected with a field bus, and used for controlling working states of the motor compressor and the heater; the in-vehicle temperature sensor is connected with the air conditioning control module and used for measuring in-vehicle temperature and supplying the measured temperature to the air conditioning control module; the air conditioning switch comprises a refrigeration switch and a heating switch, both the refrigeration switch and the heating switch are electrically connected with the air conditioning control module and respectively used for sending refrigeration and heating request signals after being triggered, and then the air conditioning module at least combines in-vehicle temperature to determine the working state of the motor compressor and the heater. The air conditioning system for the hybrid power vehicle has the advantages that a constant temperature function which is not possessed by a traditional vehicle manual air conditioning system is achieved, frequency conversion performance is possessed, energy is saved, and fuel saving ratio is improved.

Description

technical field [0001] The invention relates to an air-conditioning system for a vehicle, in particular to an air-conditioning system for a hybrid vehicle. Background technique [0002] The vehicle air conditioning system is a device that realizes cooling, heating, ventilation, etc. of the air in the vehicle. The refrigeration device of the traditional vehicle air conditioning system is mainly composed of a fuel motor driven compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator, and a blower, and is equipped with some necessary control and detection switches such as A / C switch, Internal / external circulation switch, three-position pressure switch, etc., are connected by copper tubes (or aluminum tubes) and high-pressure rubber tubes to form a closed system. During refrigeration, the refrigerant circulates in this closed system in different states. Each cycle has four basic processes: 1. Compression process: the compressor sucks the low-temperatur...
